3M 01202 216U Series Abrasive Disc Roll, 6 in Dia, P500 Grit, PSA, Gold

Our 3M™ Stikit™ gold disc roll 216U features aluminum oxide mineral abrasive for a sharp cut and uniform finish during collision repair. These tear-off discs are packed into a single roll and feature Stikit™ adhesive attachment, making them exceptionally fast and easy-to-use. Load-resistant coating and available seven-hole pattern help clear dust from the disc surface for longer life. 3M™ Stikit™ disc rolls are multiple adhesive backed abrasive discs rolled onto a core. This makes them easy to tear-off one at a time for speed and efficiency and there's no need for liners which saves on material costs. These ready to use Stikit™ discs feature a pressure sensitive adhesive coating on the backs - simply press the disc onto the backup pad and you're ready to go. They remove just as cleanly, leaving an uncontaminated surface for the next disc.
3M Stikit coated 216U PSA disc roll uses aluminum oxide as the abrasive material and has a diameter of 6 in. 3M incorporates this aluminum oxide material into the PSA disc roll forming a grit of P500. This abrasive is on a paper backing, A weight.

Abrasive Material:
Values: A/O Aluminum Oxide AO A/Z Alumina Zirconia AZ S/C Silicon Carbide SC Alumina Zirconia Alumina zirconia is very dense and can be used under high temperatures for heavy-duty stock removal, wood planing, and grinding of fiberglass and plastics. The abrasive grain is designed to fracture during use so that it maintains sharpness. Aluminum Oxide Aluminum oxide is an artificial abrasive suited for general purpose stock removal and finishing. It is the mostly commonly used abrasive and can be used for most steels and ferrous alloys. Aluminum oxide is slightly softer but tougher than silicon carbide. Ceramic Ceramic is used for aggressive cutting and grinding of stainless steel, titanium, and metal alloys. The abrasive grain is designed to fracture during use so that it maintains sharpness. Ceramic Aluminum Oxide Cerium Oxide Diamond Diamond can be either natural or manufactured and is one of the hardest abrasive materials. It is commonly used for grinding and polishing stone and very hard steels, and for sharpening other cutting tools. Mesh Silicon Carbide Silicon carbide is a manufactured material that is extremely hard but brittle. It is commonly used for fast cutting under light pressure, particularly on cast iron, nonferrous metals, and materials such as glass and plastic. Precision Shaped Ceramic Grain Zirconia
Backing Weight:
Paper and cloth have a lettering scale for backing weight that measures strength of the material onto which the abrasive is mounted. Paper uses the letters A-F, where A is a lighter weight and most flexible and F represents a rigid, heavier backing. Lighter backings are typically paired with finer abrasive grits, suitable for blending and finishing. Coarser grits used for deburring and stock removal rely on a heavier backing. Cloth uses a lettering system of J, X, and Y for backing weight. J weight (jeans) is the lightest and most flexible, X weight (drills) is more durable and recommended for medium duty work, and Y weight is the toughest and least flexible. Fiber backings are made from chemically-impregnated paper to form a very hard, strong backing material. Fiber is used primarily for sanding discs. Polyester film backing provides high strength with a very thin backing and is used for very fine grits. It is more tear resistant than paper backing and is also waterproof.
Grit:
Grit is a measurement of the size of abrasive particles embedded in coated abrasives. The most common standards for grit size are the United States CAMI (Coated Abrasive Manufacturers Institute) and the European FEPA (Federation of European Producers of Abrasives). A smaller grit number means larger particles and a coarser grade, while high number grits are used for finer work. Grit is generally a unitless measure but is sometimes measured in microns.
Grade:
Grade is a measurement of the size of abrasive particles embedded in coated abrasives. It is a more general measurement of the level of precision, and corresponds roughly to grit. A smaller grit number means larger particles and a coarser grade, while high number grits are used for finer work.
